1.  Mass Effect 1 & 2, soon to be 3 (Bioware needs to make EVERY RPG from now on)
2.  Total War series  (Realistic real time battles involving historically accurate units?  Count me in!)
3.  Half Life 1 & 2 (The expansions for 1 were meh, but still, Gordan Freeman, it's good to see you!)
4.  Fallout: New Vegas (It's Oblivion, with guns!)
5.  Battlefield 3 (Fuck you, Activision!)
6:  Supreme Commander (The first one and it's expansion, not the piece of shit second one)
7.  World in Conflict (Imagine a Tom Clancy novel, but with more action.  Lots more action.)
8.  Deus Ex:  Human Revolution  (Does anyone want to challenge this?)
9.  Halo 1-3 (Fuck ODST and Reach, fucking filler pieces of shit....)
10.  Star Wars: Battlefront  (Fuck yeah!)
